[0001] The utility model relates to the technical field of mechanical pump body sealing ring assembly tools, in particular to a mechanical pump body sealing ring assembly tool. Background Art

[0002] A mechanical pump consists of two major parts: a motor and a pump body. In an ordinary mechanical pump, the motor drives the pump shaft to rotate through a belt. In a direct-connected mechanical pump, the motor is directly connected to the pump shaft without an intermediate transmission link. A mechanical pump uses the principle of gas expansion, compression, and discharge to extract gas from a container. It is called a mechanical pump because it uses a mechanical method to periodically change the volume of the suction chamber in the pump, so that the gas in the container continuously expands into the suction chamber through the pump's air inlet, and then is discharged from the pump through the exhaust port through compression. The pump body needs to be sealed with a sealing ring.
